If this setting is activated, a link will be established between the guide points, i.e., the distance between individual points remains the same. If you move a guide’s tip, the other tips will follow. If this setting is not active, the points can be moved independently, without affecting the others (just like moving Cinema 4D spline points).
Activate this setting if you do not want guides or guide points to penetrate the hair-covered surface. This setting only affects polygon objects on which hair grows.
This is the minimum distance guides or guide elements that are moved should maintain from the hair-covered surface.
